Ok, so I'm running without enhancement at this point. > On Dec 13, 2009, at 1:56 PM, Rick Curtis wrote: > > > I'm going to suggest you spend a few more cycles on getting > > buildtime enhancement working as runtime enhanced classes has a > > number of known issues...

My attempt to set up load-time enhancement didn't work, due to struggles with classloaders and other problems. I'm hoping I can somehow get build-time enhancement working. Hopefully the JIRA I filed will make it obvious either what I've done wrong, or what's wrong with the enhancer. > > On Dec 13, 2009, at 3:53 PM, "KARR, DAVID (ATTCINW)" > > <[email protected]> wrote: > > > >>> -----Original Message----- > >>> From: Rick Curtis [mailto:[email protected]] > >>> Sent: Sunday, December 13, 2009 10:50 AM > >>> To: [email protected] > >>> Subject: Re: Issues using same domain classes in JPA and CXF/JAXB > >>> > >>> Sorry I haven't followed this chain of emails, but what type of > >>> enhancement are you using? > >> > >> Well, presently I believe I'm just using "run-time" enhancement.
